This report addresses how the production and use of bioenergy products are likely to influence the future state of water resources and asserts that bioenergy development needs be carefully planned to avoid it adding to existing pressures. It outlines circumstances in which well-planned bioenergy development can improve agricultural practices. The findings indicate that bioenergy’s water demands are in large part linked with the cultivation and processing of feedstocks, which in turn have important implications for sustainable agriculture, land use, and food production.
